Add edac_mc_add_mc_with_groups() for initializing the mem_ctl_info object with the optional attribute groups. This allows drivers to pass additional sysfs entries without manual (and racy) device_create_file() and co calls. edac_mc_add_mc() is kept as is, just calling edac_mc_add_with_groups() with NULL groups.

2012-06-12edac: edac_mc_handle_error(): add an error_count parameterMauro Carvalho Chehab1-0/+1
In order to avoid loosing error events, it is desirable to group error events together and generate a single trace for several identical errors. The trace API already allows reporting multiple errors. Change the handle_error function to also allow that. The changes at the drivers were made by this small script: $file .=$_ while (<>); $file =~ s/(edac_mc_handle_error)\s*\(([^\,]+)\,([^\,]+)\,/$1($2,$3, 1,/g; print $file; Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-06-11edac: remove arch-specific parameter for the error handlerMauro Carvalho Chehab1-2/+1
Remove the arch-dependent parameter, as it were not used, as the MCE tracepoint weren't implemented. It probably doesn't make sense to have an MCE-specific tracepoint, as this will cost more bytes at the tracepoint, and tracepoint is not free. The changes at the EDAC drivers were done by this small perl script: $file .=$_ while (<>); $file =~ s/(edac_mc_handle_error)\s*\(([^\;]+)\,([^\,\)]+)\s*\)/$1($2)/g; print $file; Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-06-11RAS: Add a tracepoint for reporting memory controller eventsMauro Carvalho Chehab1-4/+4
Add a new tracepoint-based hardware events report method for reporting Memory Controller events. Part of the description bellow is shamelessly copied from Tony Luck's notes about the Hardware Error BoF during LPC 2010 [1]. Tony, thanks for your notes and discussions to generate the h/w error reporting requirements. [1] http://lwn.net/Articles/416669/ We have several subsystems & methods for reporting hardware errors: 1) EDAC ("Error Detection and Correction"). In its original form this consisted of a platform specific driver that read topology information and error counts from chipset registers and reported the results via a sysfs interface. 2) mcelog - x86 specific decoding of machine check bank registers reporting in binary form via /dev/mcelog. Recent additions make use of the APEI extensions that were documented in version 4.0a of the ACPI specification to acquire more information about errors without having to rely reading chipset registers directly. A user level programs decodes into somewhat human readable format. 3) drivers/edac/mce_amd.c - this driver hooks into the mcelog path and decodes errors reported via machine check bank registers in AMD processors to the console log using printk(); Each of these mechanisms has a band of followers ... and none of them appear to meet all the needs of all users. As part of a RAS subsystem, let's encapsulate the memory error hardware events into a trace facility. The tracepoint printk will be displayed like: mc_event: [quant] (Corrected|Uncorrected|Fatal) error:[error msg] on [label] ([location] [edac_mc detail] [driver_detail] Where: [quant] is the quantity of errors [error msg] is the driver-specific error message (e. g. "memory read", "bus error", ...); [location] is the location in terms of memory controller and branch/channel/slot, channel/slot or csrow/channel; [label] is the memory stick label; [edac_mc detail] describes the address location of the error and the syndrome; [driver detail] is driver-specifig error message details, when needed/provided (e. g. "area:DMA", ...) For example: mc_event: 1 Corrected error:memory read on memory stick DIMM_1A (mc:0 location:0:0:0 page:0x586b6e offset:0xa66 grain:32 syndrome:0x0 area:DMA) Of course, any userspace tools meant to handle errors should not parse the above data. They should, instead, use the binary fields provided by the tracepoint, mapping them directly into their Management Information Base. NOTE: The original patch was providing an additional mechanism for MCA-based trace events that also contained MCA error register data. However, as no agreement was reached so far for the MCA-based trace events, for now, let's add events only for memory errors. A latter patch is planned to change the tracepoint, for those types of event.

2012-05-29Merge git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edacLinus Torvalds1-31/+16
Pull EDAC internal API changes from Mauro Carvalho Chehab: "This changeset is the first part of a series of patches that fixes the EDAC sybsystem. On this set, it changes the Kernel EDAC API in order to properly represent the Intel i3/i5/i7, Xeon 3xxx/5xxx/7xxx, and Intel E5-xxxx memory controllers. The EDAC core used to assume that: - the DRAM chip select pin is directly accessed by the memory controller - when multiple channels are used, they're all filled with the same type of memory. None of the above premises is true on Intel memory controllers since 2002, when RAMBUS and FB-DIMMs were introduced, and Advanced Memory Buffer or by some similar technologies hides the direct access to the DRAM pins. So, the existing drivers for those chipsets had to lie to the EDAC core, in general telling that just one channel is filled. That produces some hard to understand error messages like: EDAC MC0: CE row 3, channel 0, label "DIMM1": 1 Unknown error(s): memory read error on FATAL area : cpu=0 Err=0008:00c2 (ch=2), addr = 0xad1f73480 => socket=0, Channel=0(mask=2), rank=1 The location information there (row3 channel 0) is completely bogus: it has no physical meaning, and are just some random values that the driver uses to talk with the EDAC core. The error actually happened at CPU socket 0, channel 0, slot 1, but this is not reported anywhere, as the EDAC core doesn't know anything about the memory layout. So, only advanced users that know how the EDAC driver works and that tests their systems to see how DIMMs are mapped can actually benefit for such error logs. This patch series fixes the error report logic, in order to allow the EDAC to expose the memory architecture used by them to the EDAC core. So, as the EDAC core now understands how the memory is organized, it can provide an useful report: EDAC MC0: CE memory read error on DIMM1 (channel:0 slot:1 page:0x364b1b offset:0x600 grain:32 syndrome:0x0 - count:1 area:DRAM err_code:0001:0090 socket:0 channel_mask:1 rank:4) The location of the DIMM where the error happened is reported by "MC0" (cpu socket #0), at "channel:0 slot:1" location, and matches the physical location of the DIMM. There are two remaining issues not covered by this patch series: - The EDAC sysfs API will still report bogus values. So, userspace tools like edac-utils will still use the bogus data; - Add a new tracepoint-based way to get the binary information about the errors. Those are on a second series of patches (also at -next), but will probably miss the train for 3.5, due to the slow review process."

2012-05-28edac: Change internal representation to work with layersMauro Carvalho Chehab1-20/+79
Change the EDAC internal representation to work with non-csrow based memory controllers. There are lots of those memory controllers nowadays, and more are coming. So, the EDAC internal representation needs to be changed, in order to work with those memory controllers, while preserving backward compatibility with the old ones. The edac core was written with the idea that memory controllers are able to directly access csrows. This is not true for FB-DIMM and RAMBUS memory controllers. Also, some recent advanced memory controllers don't present a per-csrows view. Instead, they view memories as DIMMs, instead of ranks. So, change the allocation and error report routines to allow them to work with all types of architectures. This will allow the removal of several hacks with FB-DIMM and RAMBUS memory controllers. Also, several tests were done on different platforms using different x86 drivers. TODO: a multi-rank DIMMs are currently represented by multiple DIMM entries in struct dimm_info. That means that changing a label for one rank won't change the same label for the other ranks at the same DIMM. This bug is present since the beginning of the EDAC, so it is not a big deal. However, on several drivers, it is possible to fix this issue, but it should be a per-driver fix, as the csrow => DIMM arrangement may not be equal for all. So, don't try to fix it here yet. I tried to make this patch as short as possible, preceding it with several other patches that simplified the logic here. Yet, as the internal API changes, all drivers need changes. The changes are generally bigger in the drivers for FB-DIMMs. Cc: Aristeu Rozanski <arozansk@redhat.com> Cc: Doug Thompson <norsk5@yahoo.com> Cc: Borislav Petkov <borislav.petkov@amd.com> Cc: Mark Gross <mark.gross@intel.com> Cc: Jason Uhlenkott <juhlenko@akamai.com> Cc: Tim Small <tim@buttersideup.com> Cc: Ranganathan Desikan <ravi@jetztechnologies.com> Cc: "Arvind R." <arvino55@gmail.com> Cc: Olof Johansson <olof@lixom.net> Cc: Egor Martovetsky <egor@pasemi.com> Cc: Chris Metcalf <cmetcalf@tilera.com> Cc: Michal Marek <mmarek@suse.cz> Cc: Jiri Kosina <jkosina@suse.cz> Cc: Joe Perches <joe@perches.com> Cc: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Hitoshi Mitake <h.mitake@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: "Niklas Söderlund" <niklas.soderlund@ericsson.com> Cc: Shaohui Xie <Shaohui.Xie@freescale.com> Cc: Josh Boyer <jwboyer@gmail.com> Cc: linuxppc-dev@lists.ozlabs.org Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Add edac_pci_alloc_index(), because for MAPLE platform there may exist several EDAC driver modules that could make use of edac_pci_ctl_info structure at the same time. The index allocation for these structures should be taken care of by EDAC core.

2008-05-05dev_name introduction fall out fixStephen Rothwell1-1/+1
Commit 06916639e2fed9ee475efef2747a1b7429f8fe76 ("driver-core: add dev_name() to help transition away from using bus_id") added a static inline dev_name() and used it in dev_printk. Unfortunately, drivers/edac/edac_core.h defines a macro called dev_name(). Rename the latter. Diagnosis by Tony Breeds and Michael Ellerman.
